The subsurface water drainage condition was evaluated through reviewing the design drawings and construction photographs of the secondary canals and concrete box culverts. The study had revealed that the subgrade sand in several pavement areas had no connection to the secondary canals; where the passage of water from the sand layer was completely blocked. Forty-six (46) isolated blocks of pavement based on the subsurface drainage condition were identified with approximately 50% of the pavement areas suffered from water blockage.
